WA G- MACHINE.

srncrrrcnrron forming part of Letter Patent :No. 706,592, dated August 12, 1902. Application filed November 14,1901; Serial No. 82,207. (No model.)

F all whom it may concern/.-

Be it known that I, LAURA B. PARKER, of Ogden, in the county of Weber and State of Utah, have invented a new and usefulIm s provement in Washing-Machines,of which the following is a specification.

My invention relates to washing-machines of that type which employ a concave bed within an outer casing, upon which there rocks or oscillates a movable part called the rubber and which is usually formed with a convex lower surface having a corrugated or slatted face, the clothes to be washed occupying a position between the concave bedand oscil' I5 lating rubber. v

My invention isdesigned to supply said oscillating rubber with an elastic pressure in a more simple and practical manner than heretofore; and to that end it consists in a spring attachment of peculiar construction and arrangement, which is' capable of being applied to all washing-machines of the type described and which is so arranged as to be easily and quickly applied or disengaged, as may be de- 2 5 sired.

Figure l is a perspective view of a washingmachine having my invention applied to the same. Fig. 2 is an enlargeddetail side View of my attachment, showing its connection with the coacting parts of the Washing-machine. Fig. 3 is a sectional plan view on line 3 3 of Fig. 2, and Fig. 4 is a sectional detail of the screw e.

In the drawings, A represents the outer casing, B the concave bed, and O the oscillating rubber, of a washing-machine of the type referred to. per side a rigid vertical arm D, which projects up through a longitudinal slot in the 40 middle of the top of the casing and is coupled to a horizontal pitman E, which extends to the crank F ofa horizontal shaft G, and which latter at one end is provided with a balancewheel II and a crankhandle by which it is 5 turned. The rotary action of this shaftG and its crank imparts through the arm D. a. rocking or oscillating movementjto the rub- This rubber has secured to its up for passing through both the lugs a a and-the pitman', and issecured from coming out by a spring" key or cotterc. The pitman is arranged between the twolugs a a and works freely on the wrist-pin.

The projecting end of the bracket I is connected to the top of a strong helical spring J, which at its lowerend is anchored to the top portion of the Washingmachine case by a rocking bearing K, so that the tension of the spring J will be exerted upon the rubber arm D and rubber ,to hold it down with an elastic pressure upon the clothes.

The connection between the bracket I and the spring J is made by a diametrical claw d, whose hooked ends grasp, inclose, and hold the first coil of the wire spring, and through the center of this claw is tapped a screwthreaded hole that receives along set-screw e, that passes up through the end of the bracket. The shank of thi'sscrew just be low the thumb-piece is arranged to be quickly inserted in and removed from its seat in the end of the bracket by two spring seated latches'e' i, which have tapering faces that form a converging throat to give lateral passage between them to the shank of the screw. These hinged and spring-seated latches are containedin a recessed portion of the bracket and are retained by a detachable upper plate v1 which is secured by screws.

The bottom of the spring J has its last coil caught in the hooked ends of a claw j, which is formed with a clevis g, that is hinged to a Ilug 72, formed on a plate j, which latter is secured by screws or bolts tothe top of the washing-machine case.

I am aware that the oscillating rubbers of 5 some washing machines have had springs applied to the'same within the case, and also extending on the sides of the case; but I do not know that a single spring has ever been mounted upon the top of the case and ap- 10o plied to the rubber, as shown. This renders my attachment applicable to washing-machines already in use, and forms a very simple, cheap, and practical means of supplying the spring p'ressure by an external attachment, which permits its influence to be transmitted through the joint between the rubber-arm and its actuating pitman.

Having thus described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. In a washing-machine of the kind described, the combination with the arm of the oscillating rubber having a projecting wristpin; of a bracket having perforated lugs remitting quick and easy lateral engagement or disengagement substantially as described.

3. In a washing-machine of the kind described, the combination with the arm and pitman of the oscillating rubber; of abracketcoupling connected to the joint between said arm and pitman, spring-latches in the end of the said coupling, a helical spring having a diametrical claw and a screw passing through the same and also between'the latches and an anchorage for the lower end of the spring, substantially as described.

4. In a washing-machine of the kind described, the combination with the arm and pitman of the oscillating rubber; of a coupling attached to the joint of said arm and pitman, a helical spring, having at one end a diametrical claw and a stem connecting it to the coupling, and at the other end a diametrical claw with a hinged clevis adapted to connect it to the top of-the washing-machine substantially as described.
